-bindvars...NOTHING NOTHING NOTHING!
If it was needed by the query dispatcher, it would've been included.
IGNORE THEM.
(I've e-mailed more details to Kapil, but the spec didn't suggest we needed support for them in the query dispatcher, and the spec was reviewed by Dan Wickstrom and I, who both worked on the bindvar parts of the driver, i.e. we would know if support was needed so our silence wasn't entirely out of ignorance...)
